Burden of migraine in a Kuwaiti population: a door-to-door survey.

Background: Migraine prevalence and disability imprints on Kuwaiti population are underreported. We aimed to measure the prevalence of migraine and to assess its burden in Kuwait. Methods: A cross-sectional community-based study was conducted which included biologically unrelated Kuwaiti adult population aged 18-65 years. They were randomly recruited from all six governments of Kuwait using stratified multistage cluster sampling. Trained interviewers visited the samples in door-to-door approach. The Headache-Attributed Restriction, Disability, and Social Handicap and Impaired Participation (HARDSHIP) questionnaire was used to collect the data. Demographic enquires were followed by diagnostic and disability questions. Results: A total of 15,523 subjects were identified; of whom 3588 (23%) were diagnosed as episodic migraine and 845 (5.4%) as chronic headache. Prevalence of episodic migraine was 31.71% in female versus 14.88% in males ( P < 0.01) with a mean age of 34.56 ± 10.17 years. Most of migraine cohort (64.4%) sought medical advice with respect to their migraine headaches and the majority (62.4%) were seen by general practitioners (GPs) while 17.2% were assessed by neurologists and 3.7% was seen by other specialties. Tension type headache and sinus-related headaches were diagnosed in 8.9% and 2.1% of migraine subjects respectively. The majority (94.6%) of migraine subjects used symptomatic drugs for headache attacks, whereas 39.9% were taking preventive medication. In the preceding 3 months to the survey, subjects with episodic migraine had lost a mean of 1.97 days from their paid work or school attendance compared to 6.62 days in chronic headache sufferers ( P < 0.001). Additionally, subjects with episodic migraine lost a mean of 1.40 days from household work compared to 5.35 days in subjects with chronic headache ( P < 0.001). Participants with episodic migraine and chronic headache missed a mean of 2.81 and 3.85 days on social occasions, in the preceding 3 months ( P < 0.001). Conclusions: Migraine in Kuwait is highly prevalent and it has a significant impact on activity of daily living, schooling/ employment and social occasions of patients. Accurate diagnosis, effective abortive and preventive treatments of migraine are paramount to improve quality of life and as well as cost saving. [ABSTRACT FROM AUTHOR]
